We spewed so much carbon dioxide into the atmosphere and denuded so much of the planet's greenery that we succeeded in warming everything up to an even more chaotic and less predictable state.

Scientists measured how much carbon dioxide the artificially warmed plants respired — released into the air via their leaves — and learned that over time, the trees acclimated to warmer temperatures and increased their carbon emissions less than expected.

In turn, a warmer atmosphere heated the oceans making them much less efficient storehouses of carbon dioxide and reinforcing global warming, possibly forestalling the onset of a new glacial age.

The general consensus among scientists is that the young Earth's atmosphere contained much larger quantities of greenhouse gases (such as carbon dioxide and / or ammonia) than are present today, which trapped enough heat to compensate for the lesser amount of solar energy reaching the planet.

Fertilizing the surface ocean with iron increases biological productivity, but the resulting carbon dioxide removal will be much less than expected due to the increased productivity of diatoms, which incorporate and remove the bioavailable iron.

Americans will have to pay much higher electricity prices despite the minuscule benefits of the Clean Power Plan, which reduces global carbon dioxide emissions by less than 1 percent and global temperatures by 0.02 degrees Celsius by 2100, according to EPA's own models.

Natural gas is much more environmentally friendly than coal, which continues to be the mainstay of electricity production around the world and in the U.K. Gas emits less than half the CO2 per kilowatt hour produced, and it emits much lower amounts of other pollutants like nitrous oxide, sulfur dioxide, black carbon, carbon monoxide, mercury, and particulates.

[T] he author is convinced that recent increases of atmospheric carbon dioxide have contributed much less than 5 % of the recent changes of atmospheric temperature, and will contribute no more than that in the foreseeable future.

And in fact when you look at the scientific literature, it's an interesting disconnect because the modelers who study emissions and how to control those emissions are generally much more comfortable setting goals in terms of carbon dioxide and other greenhouse gas concentrations because that comes more or less directly out of their models and is much more proximate or more closely connected to what humans actually do to screw up the climate in the first place, which is emit these greenhouse gases.

[IRON STRESSED] PLANKTON FOUND TO ABSORB LESS CARBON DIOXIDE, BBC, 08/30/06 The amount of carbon absorbed by plant plankton in large segments of the Pacific Ocean is much less than previously estimated, researchers LESS CARBON DIOXIDE, BBC, 08/30/06 The amount of carbon absorbed by plant plankton in large segments of the Pacific Ocean is much less than previously estimated, researcherCARBON DIOXIDE, BBC, 08/30/06 The amount of carbon absorbed by plant plankton in large segments of the Pacific Ocean is much less than previously estimated, researchercarbon absorbed by plant plankton in large segments of the Pacific Ocean is much less than previously estimated, researchers less than previously estimated, researchers say.

Until then, it would appear that it is your assertion that the carbon dioxide filled bottle heated faster and become hotter than the air filled bottle because the carbon dioxide has a higher mass than does air, i.e., «Much smaller mass means they can hold much less heat, just as a smaller cup holds less boiling water.&raMuch smaller mass means they can hold much less heat, just as a smaller cup holds less boiling water.&ramuch less heat, just as a smaller cup holds less boiling water.»

With fewer leaves to absorb sunlight, the trees can't photosynthesise as much, and they absorb less carbon dioxide from the air.

The rise of shale gas has had an environmental benefit as well — greatly reduced carbon dioxide emissions, because generating electricity by burning natural gas emits less than half as much carbon dioxide as burning coal.

And you also knew, for example, that that an average gas driven car emitted 4.7 tons of carbon dioxide per year and an electric car would cut that in half even when powered from the current polluting grid, and much much less on a life cycle basis from a future global efficient renewable energy system displacing almost all fossil fuels.

Despite decades of persistent uncertainty over how sensitive the climate system is to increasing concentrations of carbon dioxide from the burning of fossil fuels, we now have new satellite evidence which strongly suggests that the climate system is much less sensitive than is claimed by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

The bottom line of the Bond et al. study is that the relative impact of anthropogenic carbon dioxide emissions is much less than widely thought, the relative impact of black carbon is greater than thought, and climate models» views of the past and projections of the future must therefore be tainted.

Among claims that the US airline industry is moving more people more efficiently and much more quietly than in decades past, it also claims that the «US commercial aviation industry has improved its energy efficiency, moving twelve percent more people and twenty - two percent more freight than it did in 2000, while burning five percent less fuel and producing 10 million tons less carbon dioxide.»
